This module includes various helpers that fix bugs in web servers. They may
be necessary for some versions of a buggy web server but not others. We try
to stay updated with the status of the bugs as good as possible but you have
to make sure whether they fix the problem you encounter.
If you notice bugs in webservers not fixed in this module consider

"""Implements a format decision state object that manages whitespace decisions.
Each token is processed one at a time, at which point its whitespace formatting
decisions are made. A graph of potential whitespace formattings is created,
where each node in the graph is a format decision state object. The heuristic
tries formatting the token with and without a newline before it to determine
which one has the least penalty. Therefore, the format decision state object for
each decision needs to be its own unique copy.
Once the heuristic determines the best formatting, it makes a non-dry run pass

abergeron/DeepLearningTutorials | code/convolutional_mlp.py | 4 | 12722 | """This tutorial introduces the LeNet5 neural network architecture
using Theano. LeNet5 is a convolutional neural network, good for
classifying images. This tutorial shows how to build the architecture,
and comes with all the hyper-parameters you need to reproduce the
paper's MNIST results.
This implementation simplifies the model in the following ways:
- LeNetConvPool doesn't implement location-specific gain and bias parameters
- LeNetConvPool doesn't implement pooling by average, it implements pooling
by max.
- Digit classification is implemented with a logistic regression rather than
an RBF network
- LeNet5 was not fully-connected convolutions at second layer

# This module provides unit test for the delimited text provider. It uses data files in
# the testdata/delimitedtext directory.
#
# New tests can be created (or existing ones updated), but incorporating a createTest
# call into the test. This will load the file and generate a test that the features
# loaded from it are correct. It assumes that the data is correct at the time the
# test is created. The new test is written to the test output file, and can be edited into
# this module to implement the test.

"""WebSocket extension for Apache HTTP Server.
mod_pywebsocket is a WebSocket extension for Apache HTTP Server
intended for testing or experimental purposes. mod_python is required.
Installation
============
0. Prepare an Apache HTTP Server for which mod_python is enabled.
1. Specify the following Apache HTTP Server directives to suit your
configuration.
If mod_pywebsocket is not in the Python path, specify the following.
<websock_lib> is the directory where mod_pywebsocket is installed.
PythonPath "sys.path+['<websock_lib>']"
Always specify the following. <websock_handlers> is the directory where
user-written WebSocket handlers are placed.
PythonOption mod_pywebsocket.handler_root <websock_handlers>
PythonHeaderParserHandler mod_pywebsocket.headerparserhandler
To limit the search for WebSocket handlers to a directory <scan_dir>
under <websock_handlers>, configure as follows:
PythonOption mod_pywebsocket.handler_scan <scan_dir>
<scan_dir> is useful in saving scan time when <websock_handlers>
contains many non-WebSocket handler files.
If you want to allow handlers whose canonical path is not under the root
directory (i.e. symbolic link is in root directory but its target is not),
configure as follows:
PythonOption mod_pywebsocket.allow_handlers_outside_root_dir On
Example snippet of httpd.conf:
(mod_pywebsocket is in /websock_lib, WebSocket handlers are in
/websock_handlers, port is 80 for ws, 443 for wss.)
<IfModule python_module>
PythonPath "sys.path+['/websock_lib']"
PythonOption mod_pywebsocket.handler_root /websock_handlers
PythonHeaderParserHandler mod_pywebsocket.headerparserhandler
</IfModule>
2. Tune Apache parameters for serving WebSocket. We'd like to note that at
least TimeOut directive from core features and RequestReadTimeout
directive from mod_reqtimeout should be modified not to kill connections
in only a few seconds of idle time.
3. Verify installation. You can use example/console.html to poke the server.
Writing WebSocket handlers
==========================
When a WebSocket request comes in, the resource name
specified in the handshake is considered as if it is a file path under
<websock_handlers> and the handler defined in
<websock_handlers>/<resource_name>_wsh.py is invoked.
For example, if the resource name is /example/chat, the handler defined in
<websock_handlers>/example/chat_wsh.py is invoked.
A WebSocket handler is composed of the following three functions:
web_socket_do_extra_handshake(request)
web_socket_transfer_data(request)
web_socket_passive_closing_handshake(request)
where:
request: mod_python request.
web_socket_do_extra_handshake is called during the handshake after the
headers are successfully parsed and WebSocket properties (ws_location,
ws_origin, and ws_resource) are added to request. A handler
can reject the request by raising an exception.
A request object has the following properties that you can use during the
extra handshake (web_socket_do_extra_handshake):
- ws_resource
- ws_origin
- ws_version
- ws_location (HyBi 00 only)
- ws_extensions (HyBi 06 and later)
- ws_deflate (HyBi 06 and later)
- ws_protocol
- ws_requested_protocols (HyBi 06 and later)
The last two are a bit tricky. See the next subsection.
Subprotocol Negotiation
-----------------------
For HyBi 06 and later, ws_protocol is always set to None when
web_socket_do_extra_handshake is called. If ws_requested_protocols is not
None, you must choose one subprotocol from this list and set it to
ws_protocol.
For HyBi 00, when web_socket_do_extra_handshake is called,
ws_protocol is set to the value given by the client in
Sec-WebSocket-Protocol header or None if
such header was not found in the opening handshake request. Finish extra
handshake with ws_protocol untouched to accept the request subprotocol.
Then, Sec-WebSocket-Protocol header will be sent to
the client in response with the same value as requested. Raise an exception
in web_socket_do_extra_handshake to reject the requested subprotocol.
Data Transfer
-------------
web_socket_transfer_data is called after the handshake completed
successfully. A handler can receive/send messages from/to the client
using request. mod_pywebsocket.msgutil module provides utilities
for data transfer.
You can receive a message by the following statement.
message = request.ws_stream.receive_message()
This call blocks until any complete text frame arrives, and the payload data
of the incoming frame will be stored into message. When you're using IETF
HyBi 00 or later protocol, receive_message() will return None on receiving
client-initiated closing handshake. When any error occurs, receive_message()
will raise some exception.
You can send a message by the following statement.
request.ws_stream.send_message(message)
Closing Connection
------------------
Executing the following statement or just return-ing from
web_socket_transfer_data cause connection close.
request.ws_stream.close_connection()
close_connection will wait
for closing handshake acknowledgement coming from the client. When it
couldn't receive a valid acknowledgement, raises an exception.
web_socket_passive_closing_handshake is called after the server receives
incoming closing frame from the client peer immediately. You can specify
code and reason by return values. They are sent as a outgoing closing frame
from the server. A request object has the following properties that you can
use in web_socket_passive_closing_handshake.
- ws_close_code
- ws_close_reason
Threading
---------
A WebSocket handler must be thread-safe if the server (Apache or
standalone.py) is configured to use threads.
Configuring WebSocket Extension Processors
------------------------------------------
See extensions.py for supported WebSocket extensions. Note that they are
unstable and their APIs are subject to change substantially.
A request object has these extension processing related attributes.
- ws_requested_extensions:
A list of common.ExtensionParameter instances representing extension
parameters received from the client in the client's opening handshake.
You shouldn't modify it manually.
- ws_extensions:
A list of common.ExtensionParameter instances representing extension
parameters to send back to the client in the server's opening handshake.
You shouldn't touch it directly. Instead, call methods on extension
processors.
- ws_extension_processors:
A list of loaded extension processors. Find the processor for the
extension you want to configure from it, and call its methods.

"""Represents an open transaction to the PostgreSQL DB backend,
acting as a lightweight wrapper around psycopg2's
``cursor`` objects.
``Cursor`` is the object behind the ``cr`` variable used all
over the OpenERP code.
.. rubric:: Transaction Isolation
One very important property of database transactions is the
level of isolation between concurrent transactions.
The SQL standard defines four levels of transaction isolation,
ranging from the most strict *Serializable* level, to the least
strict *Read Uncommitted* level. These levels are defined in
terms of the phenomena that must not occur between concurrent
transactions, such as *dirty read*, etc.
In the context of a generic business data management software
such as OpenERP, we need the best guarantees that no data
corruption can ever be cause by simply running multiple
transactions in parallel. Therefore, the preferred level would
be the *serializable* level, which ensures that a set of
transactions is guaranteed to produce the same effect as
running them one at a time in some order.
However, most database management systems implement a limited
serializable isolation in the form of
`snapshot isolation <http://en.wikipedia.org/wiki/Snapshot_isolation>`_,
providing most of the same advantages as True Serializability,
with a fraction of the performance cost.
With PostgreSQL up to version 9.0, this snapshot isolation was
the implementation of both the ``REPEATABLE READ`` and
``SERIALIZABLE`` levels of the SQL standard.
As of PostgreSQL 9.1, the previous snapshot isolation implementation
was kept for ``REPEATABLE READ``, while a new ``SERIALIZABLE``
level was introduced, providing some additional heuristics to
detect a concurrent update by parallel transactions, and forcing
one of them to rollback.
OpenERP implements its own level of locking protection
for transactions that are highly likely to provoke concurrent
updates, such as stock reservations or document sequences updates.
Therefore we mostly care about the properties of snapshot isolation,
but we don't really need additional heuristics to trigger transaction
rollbacks, as we are taking care of triggering instant rollbacks
ourselves when it matters (and we can save the additional performance
hit of these heuristics).
As a result of the above, we have selected ``REPEATABLE READ`` as
the default transaction isolation level for OpenERP cursors, as
it will be mapped to the desired ``snapshot isolation`` level for
all supported PostgreSQL version (8.3 - 9.x).
Note: up to psycopg2 v.2.4.2, psycopg2 itself remapped the repeatable
read level to serializable before sending it to the database, so it would
actually select the new serializable mode on PostgreSQL 9.1. Make
sure you use psycopg2 v2.4.2 or newer if you use PostgreSQL 9.1 and
the performance hit is a concern for you.
.. attribute:: cache
Cache dictionary with a "request" (-ish) lifecycle, only lives as
long as the cursor itself does and proactively cleared when the
cursor is closed.
This cache should *only* be used to store repeatable reads as it
ignores rollbacks and savepoints, it should not be used to store
*any* data which may be modified during the life of the cursor.

Program: xpt.py
Task: describe interfaces etc using XPCOM reflection.
Subtasks:
output (nearly) exactly the same stuff as xpt_dump, for verification
output Python source code that can be used as a template for an interface
Status: Works pretty well if you ask me :-)
Author:
David Ascher did an original version that parsed XPT files
directly. Mark Hammond changed it to use the reflection interfaces,
but kept most of the printing logic.
Revision:
0.1: March 6, 2000
0.2: April 2000 - Mark removed lots of Davids lovely parsing code in favour
of the new xpcom interfaces that provide this info.
May 2000 - Moved into Perforce - track the log there!
Early 2001 - Moved into the Mozilla CVS tree - track the log there!
Todo:
Fill out this todo list.

list of tuples, where each tuple has two elements:

offset_coordinates : string

'data' for data coordinates, or 'figure' for figure (pixel)

offset_order : string
either "before" or "after". This specifies whether the offset
is applied before the path transform, or after. The matplotlib
backend equivalent is "before"->"data", "after"->"screen".
styles: dictionary

# NodeList -- lightest possible NodeList implementation
#
# EmptyNodeList -- lightest possible NodeList that is guarateed to
# remain empty (immutable)
#
# StringTypes -- tuple of defined string types
#
# defproperty -- function used in conjunction with GetattrMagic;
# using these together is needed to make them work

#
# class MyClass(GetattrMagic):
# def _get_myattr(self):
# return something
#
# defproperty(MyClass, "myattr",
# "return some value")
#
# For Python 2.2 and newer, this will construct a
# property object on the class, which avoids
# needing to override __getattr__(). It will only
# work for read-only attributes.
#
# For older versions of Python, inheriting from
# GetattrMagic will use the traditional
# __getattr__() hackery to achieve the same effect,
# but less efficiently.
#
# defproperty() should be used for each version of

Package resource API
--------------------
A resource is a logical file contained within a package, or a logical
subdirectory thereof. The package resource API expects resource names
to have their path parts separated with ``/``, *not* whatever the local
path separator is. Do not use os.path operations to manipulate resource
names being passed into the API.
The package resource API is designed to work with normal filesystem packages,
.egg files, and unpacked .egg files. It can also work in a limited way with
.zip files and with custom PEP 302 loaders that support the ``get_data()``
method.
